Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention group will participate in a home based balance exercise programme, provided at home by an experienced physiotherapist. This exercise programme is modified from an existing home exercise programme “Otaogo programme” to suit people with memory difficulties, and will be tailored to the results of the balance and mobility assessments. The Otago programme has been shown in a number of studies of older people to reduce falls. The exercise programme will be structured to be performed at least 5 times each week, and will have a focus on standing balance and strengthening exercise, as well as a graduated walking programme. The physiotherapist will provide six home visits over the six month period, to monitor, advise, and modify the programme as required. The frequency of home visits in this study is slightly increased on the successful Otago programme (4 visits), aiming to maximise safety with increased visits particularly in the first 6-8 weeks of the programme. An exercise booklet will be provided by the physiotherapist to each pariticipant to give illustrations and instructions for the participant to continue the exercise programme at home. In between visit, the physiotherapist will contact participant by telephone.

Rehabilitation
Comparator / control treatment
There will be 3 sub-groups of participants. One intervention group (107 patients with recently diagnosed Alzheimer's dementia) will be provided with a home based balance exercise program. A futher 107 patients with recently diagnosed Alzheimer's dementia will receive a home occupational therapy programme involving six home visits for the six month duration by an experienced Occupational Therapist, to provide an information / education programme focusing on a mixture of social activities, psychological support, and maintenance of Activities of Daily Living advice. This programme will be based on a programme for people with dementia by Graff et al (2007). These Occupational Therapy (OT) home visit sessions will avoid any messages encouraging change in activity.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be informed about the study by a geriatrician at the CDAMS Clinic at the time or shortly after the time a patient is diagnosed with Alzheimer's disease. They will obtain permission from the participant or the person responsible for the research team to contact them about the research project. Following contact by the research team, and agreement to participate, participants who finish the baseline assessment will be allocated to one of the two intervention groups by a research assistant who is independent of the assessors. She will communicate with the participants and their caregivers and advise them which group they are in and the next phases of the project. Allocation was concealed by using numbered opaque envelopes, the next consecutive one opened for each consecutive participant.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Random numbers table generated by a computer software to determine group allocation for each participant ID number.
